1. Your hypothesis test for a mean with n = 17 has a left-tailed critical region. The test statistic is t = -1.38. Find the p-value accurate to 2 decimal places.
p-value =
2. You are performing a right-tailed t-test with a sample size of 31. If α = 0.005, find the critical value, to two decimal places.
3. You are performing a left-tailed t-test with a sample size of 7. If α = 0.025, find the critical value, to two decimal places.
4. Testing:
H0: p = 0.81
H1: p ≠ 0.81
Your sample consists of 76 subjects, with 60 successes. Calculate the test statistic, rounded to 2 decimal places.
5. Testing:
H0: μ = 60.42
H1: μ ≠ 60.42
Your sample consists of 43 subjects, with a mean of 59.7 and standard deviation of 4.55.
Calculate the test statistic, rounded to 2 decimal places.
